The Australians are blowing up the claims of identity theft by the Australian/Israelis. Apparently Mossad would send these people back to Australia to change their names to more anglo sounding names.

Therefore those claiming identity theft will always be suspected of being Mossad agents and may in fact get busted by their home countries for it.
